Product Description
Built for precision in confined jobsites, this 2020 Komatsu PC58-8 mini excavator delivers 5.4-ton performance with exceptional operator control. Powered by a reliable S4D87E-1 water-cooled engine producing 36 kW at 2300 rpm, it combines responsive hydraulics with a compact 1960 mm transport width for versatile applications in urban construction and utility work.
Operators benefit from commanding visibility across a 6120 mm maximum digging radius and 3800 mm depth capability. The spacious cabin provides clear sightlines to the 725 mm bucket and surrounding work area, while intuitive pilot controls manage 26.5 MPa working pressure through a variable capacity piston pump. Smooth 9.0 rpm rotation speed and balanced 30.8 kPa ground pressure ensure stable positioning on sensitive surfaces.
- Working weight: 5400 kg with 0.23 m³ bucket capacity
- Digging force: 39 kN bucket / 23.9 kN arm for tough soil conditions
- Compact dimensions: 5935 mm length, 2550 mm height when transported
- Efficient fuel system: 120 L tank supports extended shifts
- Currently located in Luzhou, Sichuan – ready for international export
